300 calories a DAY: Portia de Rossi cries to Oprah as she reveals shocking details of her anorexia

Portia de Rossi has sat down for a tearful interview with Oprah in which she discusses the depths of her anorexia and how she was almost 'proud' of dropping to under six stone, weighing in at just 82 lbs.

De Rossi, who has changed her name to Portia Degeneres since marrying partner Ellen Degeneres, choked up while promoting her memoir 'Unbearable Lightness: A Story of Loss and Gain.'

'It wasn't that I was proud of it,' she tells Oprah in the interview airing in the U.S. on Monday. 'But it was certainly a recognition for my self control.'
